Fuel Saving Tips
Don't assume your ecu will latch a fault. My GSF650K9 has a fault code for a faulty O2 sensor. I have had no fault light but some time in the last year the sensor has gone bad. even with the engine dead I got 4.7 volts out of the sensor, with the engine running 4.7 volts. ecu reads that as lean and adds fuel. How long has it been duff?Looking at my drooping economy figures I'm guessing the last 3 months. Did I check the other sensors? You bet.
